Rating of the best bimetallic heating radiators for 2024

Bimetallic heating radiators - how does the new product differ from traditional options? Massive cast iron batteries looked aesthetically pleasing, while aluminum counterparts quickly lost their original luster. In addition, the first species had a high heat transfer, in contrast to its aluminum counterparts. Bimetal is a compromise between lightweight aluminum and massive cast iron batteries, which were in great demand 50 years ago. Modern designs are more technologically advanced, have their own characteristics and disadvantages. They differ among themselves in size and cost.

Feature of the material used

First of all, you need to pay attention to the fact that the radiator is reliable. A stainless steel product would be an excellent solution. However, such material belongs to the category of expensive, heavy and extremely difficult to process. When a battery is made from this type of corrosive material, there will be no variety of shapes. It also implies redundant reliability, which is extremely disadvantageous for the manufacturer.

The addition of aluminum will help make the machining process less costly and labor intensive. Such material is easily cast and is considered not only immune to corrosion, but also to electrochemical decomposition. This alloy is classified as light. In addition, he is not able to withstand regular dynamic influences.

However, over time, a solution was found. It was decided to fix the steel manifold inside the mold. The chosen form was simple, which made it possible to carry out the assembly even for a person who is not distinguished by professionalism. After the aluminum alloy mold was pressed in, the embedded element remained inside the structure and became the second skin. Thus, the transfer of heat was carried out without obstacles. And the body of the bimetallic device itself was reliably protected from influences from the coolant.

The modern buyer needs to pay attention to factors that will help to find a high-quality bimetallic radiator. Products must meet the following parameters:

1. Gaskets and nipple connections must be secure. Even after years of operation, they must remain tight at moments of sudden temperature surges.
2. Injection molding is considered to be the key to the formation of a quality product.It is extremely important not only preparatory work, but also compliance with the established proportions.
3. A steel liner of normal thickness is required to withstand abrasion.
4. High manufacturability of manufacturing, welding and forming, which are carried out exclusively on modern equipment. This reduces the risk of internal stress. For heating systems, this aspect is extremely important.
5. There are a number of welding rules that apply to each of the key structural elements.
6. Placement of threaded bushings on the manifolds, not just tubular inserts that were placed in the section channel. In fact, the principle of using the embedded element has changed.

When such costs are justified

The use of modern technologies makes it possible to achieve the manufacture of both durable bimetallic and aluminum radiators. We are not talking about the price. However, the question is still urgent, because such spending should be justified. First of all, we are talking about technical necessity. The meaning of installing bimetallic structures is present only when the embedded element, which is located inside the heating system, will perform at least several tasks from the general list of possible ones.

In particular, we are talking about heating systems that do not use a water treatment unit. It is also possible to use an unusual type of coolant, which is characterized by the presence of a more aggressive environment. In this case, the purchase of bimetallic batteries will be more than justified, because there will be no need to purchase expensive equipment that is used to regulate the acidity of the environment. In addition, such ancillary equipment allows both mechanical cleaning and filtration of cations.

Mechanical impact is also considered an important factor. This can result in pressure surges during operational changes, pressure testing and system make-up. Similar phenomena are observed in centralized heating systems, which are classified as communal facilities. What should you also pay attention to? It's about a safety margin. For bimetallic radiators, it is high.

The only limitation is considered to be the requirement for high inertia of the system used. This will be of particular importance in the event that the heat carrier of the building structure is small, and the thermal insulation is of high quality. Thus, cast iron will help smooth out daily temperature differences. However, its zonal flexibility falls short of expectations.

It should also be remembered about temporary losses when heating batteries of this type. Steel has a higher heat capacity. However, one should not forget about the specific layer between the body and the heat exchanger. If high-quality Italian and Russian-made products are used, then this indicator can be leveled in several ways. The response time required to recognize a change in thermal head is reduced by 2-5% compared to the same aluminum units. Chinese-made equipment is not designed for such tricks.

Selection recommendations

In order to determine the place where to buy radiators, you need to flip through the catalogs of several online stores.Thus, you can get an idea about each of the types of products on the market today. It will also help to identify the average price for the sample you like. However, you should not give preference to little-known manufacturers and expensive new products. Perhaps the sample you need is produced by a domestic concern.

There are only four materials from which water convectors are made:

1. Bimetal (monolithic units consisting of a certain number of sections).
2. Cast iron.
3. Aluminum.
4. Steel.

When choosing a unit, you should correctly select its power. To do this, you will need to independently calculate the required amount of heat and the available standards for the supply. There are several ways to accomplish your plans. It is possible to use data regarding the volume of the room and the heat loss of the building.

Step by step instructions on how to choose a water convector

1. Popular models can be suitable for all characteristics, but their cost will be appropriate. It is necessary to stop at the "golden mean". You should not buy equipment that is too cheap, and the most expensive may not be necessary.
2. Attractiveness alone may not be enough. The selected model must be suitable in terms of functionality, color, size (height) and connection method. The battery should look organic not only in the room itself, but also fit into the niche intended for it.
3. Before you buy and then install a battery in a high-rise building, you need to make sure that the heating section is suitable for the declared characteristics. In this case, the operating pressure of the unit must be less than 12 atmospheres. Such information is contained in the description of the product and its passport.

It should be noted that in most cases, the installation of radiators is carried out independently at home. In this case, you need to make sure that DIY installation is possible. Also, the set should contain the necessary jumpers and auxiliary components that the master will need.

4. But for private houses, this aspect is not considered so important. Such characteristics are not taken into account during the construction and subsequent installation of the heating system. The exception is coal or wood-fired boilers, which are responsible for heating. In this case, it is necessary to buy a sample that can function in the presence of a high temperature coolant. The higher the number, the longer the batteries will last.
5. The popularity of the models is important, but not as much as the way of connecting the radiator itself. It is much more convenient for the subsequent repair and connection of the lower connection. This will make it easier to hide existing pipes. The lateral type of connection means that the pipes will be walled up into the walls (it is not possible to fix the breakdown later without further repair) or remain in plain sight.
6. There may be several options for mounting the device. Not only wall models are in demand, but also no less high-quality floor ones. The complete set will play an important role and it is worth paying special attention to this. It is somewhat easier to have a jumper from the same manufacturer on hand, compared to one that was bought at random at a local store. The latter option may not fit at all in size. The basic kit should contain the fittings and brackets. Otherwise, you will have to buy everything yourself.

It is worth noting that Mayevsky valves and tap are often bought separately. You should not look for such attributes in the kit. After choosing a model, you can proceed to the selection of equipment of the appropriate capacity.

Conclusion

First of all, when buying new heating radiators, you should pay attention to the main material from which they are made. It is not recommended to use aluminum and steel, since the first option suffers from accelerated corrosion, while the second one - from the slightest pressure drops. Bimetallic structures are significantly more expensive than similar types of products. However, if first of all you pay attention to indicators such as durability, quality and reliability, then bimetallic radiators cannot be found better. It is advisable to pay once and not face breakdowns for 10-25 years, than to buy a less reliable device, and call the master before the onset of the next heating season.
